Hallo,
Nein, muß sie nicht.
The format of a URI value is 'url(' followed by optional whitespace followed by an optional single quote (') or double quote (") character followed by the URI itself, followed by an optional single quote (') or double quote (") character followed by optional whitespace followed by ')'. The two quote characters must be the same.
(siehe http://www.w3.org/TR/REC-CSS2/syndata.html#value-def-uri)
single- oder double-quote ist __optional__.
Tatsächlich. Hm Ok ich lasse mich immer sehr gerne eines besseren belehren, danke schön.
